Match List I with List II of electromagnetic waves with corresponding wavelength range.
$$\begin{array}{|l|l|l|l|}\hline & \text{List I} & & \text{List II} \\ \hline \text{A.} & \text{Microwave} & \text{I.} & 400\ \text{nm to }1\ \text{nm} \\ \hline \text{B.} & \text{Ultraviolet} & \text{II.} & 1\ \text{nm to }10^{-3}\ \text{nm} \\ \hline \text{C.} & \text{X-ray} & \text{III.} & 1\ \text{mm to }700\ \text{nm} \\ \hline \text{D.} & \text{Infra-red} & \text{IV.} & 0.1\ \text{m to }1\ \text{mm} \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (A) A-IV, B-I, C-II, D-III
Microwaves $0.1\ \text{m}$–$1\ \text{mm}$ (IV); UV $400$–$1\ \text{nm}$ (I); X-rays $1$–$10^{-3}\ \text{nm}$ (II); infra-red $1\ \text{mm}$–$700\ \text{nm}$ (III).
